For sending the same message to 100 devices via c2dm,
We need to do the following things,
1. get registration of each device that you need to send messages.
2. initiate 100 request one for each device and send it to c2dm.
Am i correct?
Do we really need to send 100 request one for each device. one request containing registration id of each device?
Is there any way that i can send all the device’s registration ids in a single request with the message? so that with that request, c2dm will broadcast or push that common message to all 100 devices with that registration ids that it obtained in a single request?
C2dm does not allow batch sending until now. So you still have to send them for each device.
